Abstract
A deployment system is provided for utilization onboard an airborne object including a deployable element. In one embodiment, the deployment system includes a circumferential restraint and a release mechanism mounted to the airborne object. The circumferential restraint is disposed at least partially around the airborne object in a constraining position wherein the circumferential restraint prevents deployment of the deployable element. The release mechanism normally resides in a first position in which the release mechanism maintains the circumferential restraint in the constraining position. The release mechanism is movable to a second position to release the circumferential restraint from the constraining position and permit deployment of the deployable element.
Claims12
A deployment system for utilization onboard an airborne object including a deployable element, the deployment system comprising:
- a circumferential restraint disposed at least partially around the airborne object in a constraining position wherein the circumferential restraint prevents deployment of the deployable element, a portion of the circumferential restraint following a serpentine path in the constraining position;
- a pin actuation mechanism, comprising:
- a casing mounted to the airborne object;
- and
- a pin slidably mounted to the casing, the pin normally residing in an extended position wherein the pin engages the circumferential restraint to maintain the circumferential restraint in the constraining position, the pin movable to a retracted position to release the circumferential restraint from the constraining position and permit deployment of the deployable element;
- and
- a guide member mounted to the airborne object, the guide member engaging the circumferential restraint in the constraining position to help guide the circumferential restraint along the serpentine path.
A deployment system for utilization onboard an airborne object comprising a body and a rotor collar disposed around the body and configured to rotate relative thereto, the deployment system comprising:
- a canard mounted to the rotor collar;
- an elongated flexible restraint circumferentially disposed around a first section of the airborne object and normally residing in a constraining position wherein the elongated flexible restraint prevents deployment of the canard and rotation of the rotor collar;
- and
- a pin actuation mechanism, comprising:
- a casing mounted to the airborne object;
- and
- a pin slidably mounted to the casing, the pin normally residing in a first translational position wherein the pin engages the elongated flexible restraint to maintain the elongated flexible restraint in the constraining position, the pin movable to a second translational position to release the elongated flexible restraint from the constraining position and permit deployment of the canard;
- wherein the elongated flexible restraint comprises a retention cable twist-tightened around the canard and the rotor collar.
A method for equipping an airborne object with a deployment system, the airborne object including at least one deployable element, the method comprising the steps of:
- placing the deployable element in a non-deployed position;
- disposing a circumferential restraint around the airborne object in a constraining position wherein the circumferential restraint physically prevents deployment of the deployable element;
- mounting a pin retraction mechanism to the body of the airborne object, the pin retraction mechanism normally residing in an extended position wherein the pin retraction mechanism engages the circumferential restrain to maintain the circumferential restraint in the constraining position, the pin mechanism movable to a retracted position wherein the pin retraction mechanism releases the circumferential restraint from the constraining position and permits deployment of the deployable element;
- and
- forming a guide post projecting from the airborne object at a location substantially axially aligned with the deployable element and axially offset from the pin retraction mechanism, the guide post engaging the circumferential restraint to guide a portion of the circumferential restraint along a serpentine path.
